Xi'an spot ZW32-12G / 630A high-voltage vacuum circuit breaker

Detailed Description ZW32-12 / 630-20 outdoor high-voltage vacuum circuit breakers: ZW32-12 / 630-20 outdoor high-voltage vacuum circuit breaker ZW32-12 / 630-25 outdoor column vacuum circuit breakers Product Overview ZW32 column vacuum circuit breaker Outdoor (below) is the rated voltage 12KV, three-phase AC 50Hz outdoor high voltage distribution equipment. Mainly used for breaking, closing power system load current, overload current and short circuit current. For substation and industrial and mining enterprises distribution system for protection and control purposes, more suitable for urban, rural power grid construction and transformation and frequent operation place. Use of environmental conditions 1, altitude: ≤2000m and below; 2, ambient air temperature: up to + 30 ℃, the lower limit of -40 ℃; 3, air pressure does not exceed 700Pa (equivalent to wind speed 34m / s); 4, amplitude: impermanence rattling; structural features 1, three-phase circuit breaker pillar structure, a stable and reliable breaking performance, no fire and explosion hazards, maintenance-free, small size, light weight and so long service life. 2, the circuit breaker fully enclosed structure, good sealing performance, help to improve the moisture, condensation performance, especially for use in cold or wet areas. 3, three-phase current transformer pillars and imported outdoor epoxy resin solid insulation, or mining within the user epoxy solid insulation outsourcing silicone rubbers; high temperature resistant, UV resistant, anti-aging characteristics. 4, the actuator using miniaturized spring actuator, small storage motor power, low energy consumption sub-closing; institutional real motion transmission drive with a small number of parts, and high reliability. Actuator mechanism placed in a sealed box, to solve the problem of corrosion actuator to improve the reliability agencies. 5, the circuit breaker opening and closing operation can be manual or electric operation and remote remote control. With intelligent controller supporting implement distribution automation, the controller can also coincides with the composition of automatic recloser, sectionalizer. 6, the circuit breaker may be provided two-phase or three-phase current transformer for overcurrent or short-circuit protection, can also provide a current pickup signals to the intelligent controller; according to user requirements can be equipped with metering current transformer. 7, can take away the three-phase circuit breaker interlocking isolation switch, isolation switch opening states are visible fracture, and have anti-error interlock between the body and the circuit breaker, and only in isolation knife fully closing or fully when opening the circuit breaker is operable. Surge arresters can be connected with the post insulators, and easy maintenance. ZW32-12 Product Overview ZW32-12 outdoor high voltage vacuum circuit breaker (also known as: outdoor column vacuum switch) for three-phase AC 50Hz, rated voltage of 12kV power system can be breaking, closing the line load current, overload current and short circuit current. Mainly used for breaking, closing electronic system load current, overload current and short circuit current. For substation and industrial and mining enterprises distribution system for protection and control purposes, and rural power grids frequent operation place. But also as a grid disconnect switches, after the installation of the controller, can realize distribution automation, ZW32 vacuum breaker, according to user requirements, optional CT overcurrent protection, isolation switch, outdoor PT, intelligent controller (see Watchdog), metering tank means, to meet the needs of a variety of occasions. Vacuum circuit breaker in accordance with the operating mechanism, is divided into two spring operating mechanism and the permanent operator. Model ZW32-12T and ZW32-12M.
